It is preferably of U-shape in cross section and thus has spaced legs or feet stabilizing its supporting action.

The rug 15 is preferably arranged to come into approximate contact with the supporting structure for aesthetic purposes.

The supports or sections 13 may also be provided to compensate for the different thicknesses of rugs and the like that may be encountered in use, and also provides a means whereby the standard threshold plate may be used in very numerous ways and under all ordinary conditions met with.

In Figure 2, the threshold plate is pro vided with a supporting section 13 under each edge of the same. The sill 6 and the floor 8 are on the same level, and the threshold plate is fixedly mounted in such a way, that the plate 2 on the door 1, clears the top of the rug 15 on the floor 8 when the door opens.

In the modified form shown in Figure 3 thethreshold plate 15 is provided with a groove 16, and the supporting member 17 is provided with a tongue or rib 18, the groove and tongue or rib forming an interlock.- Otherwise, the structure is the same as that shown in Figure 1.

In the modified form shown in Figure 1 the threshold plate 18, is provided at its edge with grooves 19 and the supporting member 20 is provided with complemental rib portions 21 to form an interlock, of considerable superficial area. Otherwise, the structure is the same as that shown in Figure 1.

The supports or sections 13 will be of various heights, and a suitable assortment of sizes may be kept in stock.

It will be seen that in each instance there is an interlocking relationship maintained between the top surface of the supporting member 13 and the threshold member A, this relationship being maintained specifically by the inter-engagement of the rib 14 with the edge of the threshold member, although, obviously, the rib 14 might be disposed upon the threshold member instead of the support and caused to interlock with the support in correspondingly reverse manner to that specifically shown and illustrated in the drawings. It will be further apparent that this interlocking engagement between the supporting member and the threshold is effected at the outer edges of the threshold and acts to prevent any tendency of the threshold to spread and thus become distorted in the event that the threshold is tread upon, as will be inevitably the case when in use. This element therefore assures the threshold member A being permanently maintained in shape.

The embodiments of the invention illustrated and described herein have been selected for the purpose of clearly setting forth the principles involved. It will be apparent, however, that the invention is susceptible of being modified to meet the different conditions encountered in its use as to sizes and shapes of parts used, generally, and I therefore aim to cover by the appended claims all modifications within the true spirit and scope of my invention.

WVhat I claim as new and desire to secure by Letters Patent of the United States, is

In means of the class set forth, in combination, a threshold member for doors comprising a door engaging member having outwardly sloping sides, an elevating support disposed beneath an edge of at least one of the sloping sides of the door engaging member and upon which the member rests in a position determined by the said support, and means for interlocking the door engaging member and elevating support in edge to edge engagement, the interlocking means tending to restrain any tendency of the door engaging member to spread under influence of pressure exerted thereon.

2. In means of the class set forth, in combination, a threshold for doors comprising a threshold member having outwardly sloping sides,-an elevating supporting member disposed beneath an edge of at least one of the sloping sides of the threshold member and upon which the threshold member rests in a position determined by the said supporting member, the said support being of somewhat U-form in cross section to form a stable base, and means upon one of the said members for interlocking with the other of the said members to secure the said members in interlocked relationship while restraining any tendency of the door engaging member to spread under influence of pressure exerted thereon.

3. In means of the class set forth, in co1n bination, a threshold for doors comprising an integralthreshold member having outwardly curving sides, an elevating support disposed beneath an edge of one of the curving sides of the threshold member and upon which the threshold member rests in a position determined by the said support, the support having its'upper surface ribbed to interlock the support with the threshold through interlocking engagement between the ribbed surface of the support and the edge of the threshold, the ribbed surface restraining any tendency of the threshold member to spread under influence of pressure exerted thereon.

4. In means of the class set forth, in combination, a threshold for doors comprising a threshold member having outwardly di verging sides, and an elevating support disposed beneath an edge of at least one of the sides of the threshold and upon which the threshold rests in a position determined by the said support, the said support being of somewhat Uform in cross section to form a stable base, the support being provided on its top surface with a longitudinal rib to engage the edge of the threshold member and aline the same with the support, the rib interlocking with the edge of the threshold member and v restraining any tendency thereof to spread 5 under influence of pressure exerted thereon. 5. In means of the class set forth, in combination, a threshold for doors comprising a threshold member having outwardly curving sides, means to elevate the threshold including two sections beneath the curvedsides of the threshold, there being one section beneath each longitudinal edge of each side of the threshold, and means interlocking each section with the threshold member for restraining any tendency of the threshold member to spread under pressure exerted thereon.

6. In means of the class set forth, in combination, a threshold for doors comprising a threshold memberhaving outwardly curving sides and means to elevate the threshold including two sections beneath the same, one section beneath each longitudinal edge of the curved sides of the threshold, each section being formed with an integral rib extending longitudinally thereof its entire length to provide an interlocking engagement with the threshold portion seated thereon, each rib cooperating to resist tendency of the threshold to spread under pressure exerted thereon. 7. In means of the class set forth, in combination, a threshold for doors comprising an integral threshold member having outwardly diverging sides and means to elevate the threshold including two sections beneath the same, one section beneath each longitudinal edge of the diverging sides of the threshold, each section being formed with an integral rib extending longitudinally thereof its entire length to provide an interlock 40 ing engagement with the tlii'eshold portion seated thereon, the sections being of the U-form in cross section to provide spaced stabilizing legs, each section being held in position by the interlocking engagement between the edges of each side of the threshold member and the ribbed top of the section upon which the side of the threshold member rests, whereby sections of varying heights may be inserted under the edges of the threshold member to vary the heights thereof, each rib cooperating to resist tendency of the threshold to spread under pressure exerted thereon.

.In testimony whereof I af'ux my signature.
